Description
По известным способам отгонка хлористого водорода из ооллмой кислоты осуществл етс либо по принципу простой отгочки, либо гутем применени дефлегматора дл образовани флегмы, которую затем возвращают в ректификационную колонну.According to known methods, the removal of hydrogen chloride from oolmoic acid is carried out either by the principle of simple otgochki or by using a reflux condenser to form a phlegm, which is then returned to the distillation column.
Последний способ, как и первый, не дает надлежащего эффекта, так как образующа с флегма составл ет ограниченное количество примерно 20% от веса выдел емого хлористого водорода. К тому же малый объем флегмы требует тарельчатой конструкции укрепл ю хей части колонны и обуславливает низкий коэффициент теплопередачи в теплообменнике-дефлегматоре.The latter method, like the first, does not give the proper effect, since the reflux produced is a limited amount of about 20% by weight of the emitted hydrogen chloride. In addition, a small amount of reflux requires a plate-like structure that strengthens the core of the column and causes a low heat transfer coefficient in the heat exchanger-dephlegmator.
Предлагаемый способ лишен указанных недостатков и состоит в том, что роль флегмоной жидкости играет часть исходной сол ной кислот, специально задаваемой в дефлегматор-абсорбер.The proposed method is devoid of the indicated disadvantages and consists in the fact that the role of cellulitis fluid is played by a part of the initial hydrochloric acid, which is specially specified in the reflux condenser-absorber.
Исходна сол на кислота насыщаетс в дефлегматоре-абсорбере хлористым водородом и на выходе из него имеет тот состав, что и естественна флегмова жидкость. При флегмовом числе 1,2 (за счет искусственной флегмы, близкой к 1) достигаетс наиболее выгодное использование расходуемого холода и тепла, а также теплообменной i:oверхности .The initial hydrochloric acid is saturated in the reflux condenser with hydrogen chloride and at the outlet of it has the same composition as the natural reflux liquid. With a reflux ratio of 1.2 (due to artificial reflux close to 1), the most advantageous use of the consumed cold and heat, as well as heat exchange i: o the top, is achieved.
Отличительна особенность иредлагаемого способа состоит в том, что процесс отгонки ведут с применение.м искусственной флегмы, которую создают укреплением части исходной сол ной кислоты в дефлегматоре-абсорбере .A distinctive feature of the proposed method is that the distillation process is carried out with the use of artificial phlegm, which is created by strengthening part of the initial hydrochloric acid in the reflux condenser-absorber.
Пример. Осуществление процесса по сн етс схс.ой. Псходна 32%-на сол на кислота раздел етс на 2 потока: поток а- 310 кг/час; поток б-50 кг/час. Пот .ж а подогреваетс в кип тильнике от 65 до 80° и далее поступает на тарелку питани ректификационной колонExample. The implementation of the process is explained in cc. The initial 32% hydrochloric acid is divided into 2 streams: a stream a - 310 kg / h; flow b-50 kg / hour. The pot is heated in a boiler from 65 to 80 ° and then fed to the food plate of the distillation column.
